Macroeconomic Analysis of Export Diversification in Nigeria
Get PDFIn this paper, the Theil index was utilized to study the impact of macroeconomic variables on diversification in Nigeria for the period 1981-2015, using the bounds test approach to cointegration on data generated from secondary sources. Cointegration was found to exist between the economic diversification indicators and associated variables. We also found that capital formation, real effective exchange rate, domestic credit to private sector and foreign direct investment promote diversification. Government efforts in Nigeria should be geared towards diversifying the economy using oil revenue, promote foreign direct investment in the non-oil sector, provide fixed capital, encourage the flow of credit to the private sector, and implement a cautious exchange rate regime
POLICY INTERACTIONS AND THEIR IMPACT ON NIGERIA’S STOCK MARKET PERFORMANCE
No full textThe paper analyzes the interactions of macroeconomic policies and their impact on Nigeria’s stock market performance, using annual data for the period 1985-2012, generated from secondary sources. The empirical investigation was implemented through a vector error correction model. Market returns were found to be positively related to money supply and real gross domestic product and inversely associated with fiscal deficits, inflation, interest and exchange rates. Overall, money supply, fiscal deficits, inflation and exchange rates were found to be significant determinants of stock market performance. A deliberate policy initiative is called for which ensures a vibrant real sector of the economy as a measure to boost local production, promote exports, create employment and curtail inflation, all of which would make for a robust stock market
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
ASSESSING THE LONG-RUN IMPACT OF INSTITUTIONS ON ECONOMIC GROWTH: THE NIGERIAN EXPERIENCE
Get PDFThis paper investigates the long run impact of institutions (proxied by rule of law, property rights and political terror) on Nigeria’s economic growth from 1981 to 2017, using the Dynamic Ordinary Least Squares technique on annual data obtained from secondary sources. A long-run relationship was found between the explanatory variables and economic growth. The empirical evidence is in favour of a statistically significant and positive relationship between property rights and growth. Law and order was found to be statistically significant and positively associated with growth, while political terror exerted a negative impact on growth in the period of investigation. Deepening of institutions through well-developed property rights is recommended, including the enthronement of law and order to provide a mechanism for dealing with political terror, strengthen public trust and confidence and thus promote economic growth
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Economic growth, Unemployment and Poverty: Implications for Inclusive Growth Architecture in Nigeria
Get PDFThis study investigates the impact of economic growth on employment and poverty in Nigeria, as a first approximation towards inclusive growth architecture. Using the Ordinary Least Squares regression, growth was found neither to have raised the level of employment nor reduced poverty in Nigeria under the period of investigation. An increase in growth rate is associated with a rise in poverty and unemployment, although not statistically significant. The findings are suggestive of public policy targeted at increasing the level of growth which raises the level of employment and reduces poverty, as a precursor to an inclusive growth organogram for Nigeria
